ORCHARD-HEATER.

Specification of Letters Patent.

Serial No. 181,975.

To 11/! n-lmm if may rower/1.

a subject of the King of England, and Earn. N. PERPY. a ritizen of the. United States, residing at Oakland. in the rounty of Alameda and State of California have invented new and useful Improvements in Orchard Heaters, of whit-h the following is a specification.

This invention relates to orchard heaters, and pertains especially to a novel, simple means for etfet-ting a down draft upon and over the oil fuel to eti'ect perfect. combustion. 4

The invention consists of the parts and the ronstrurtion and (-onihination of parts as hereinafter more fully desrrihed and rlaitued. having referenee to the accompany ing drawings, in whirh Figure l is a vertieal sertion on line XX of Fig. 2. Fig. 2 YY of Fig 1.

A is a litpiid fuel containing rereptarle of suitahle size and shape having a tight fitting rover 2. provided \vitha gas outlet 3. Suitahly supported on the rover and extending upwardly therefrom and surr unding the gas outlet 3 is a short inner stark -t whit-h is rlosed at the top h v a eowl plate 5 for the purpose of direeting the gases generated within the through a series of small"perforations G which are made around the top of the inner stat-k. t

T is an outer stark spared from the inner stark and rirrumferentially supported on the rover extending ronsiderahly ahove the rlosed or rhoked end of. the inner stark having a series of perforations 8 ar und its hase. The regulation of air through the holes H is arromplished h v a perforated sleeve damper .l.

10 is a rover vent in the rover. primarily designed for ignition purposes and also serving as an air duet for admitting air into the rereptaele.

novel feature of the present invention is the use of an external air tuhe ll whit-h is adapted to teleseop with a. flange 12 whit-h surrounds theair inlet 13 in the rover. This tuhe ll projeets outwardtv from the rover and is of sutlit-ieut length and size and is so positioned that under the iutluenre of the draft indured through the stark T a eurrent of air will he drawn-in through tnhe it andswept downwardly in a dirertion h is a eross sertion on line rereptaeleradially outwartl' l t t l l l r ward the bottom of the receptacle and com- Be it known that we.

mingled with the gases evolved or generated within the rereptaele, and close to the surfa're of the liquid fuel. The two tubes 7 and 11 art in conjunction and as an inverted siphon to draw the. air into the receptacle and imparts the desired velocity to the air.

The tuhe imparts direction to the air rurrents-uso that the inertia of the incoming air heing ata sutlieient velocity and directed in a definite dirertion is rarried to the surfare of the oil and finally to the bottom of the pot as the oil recedes. thus enabling the heater to he burned outclean.

The. sizes and proportions of a partieular heater of this sort would he approximately as f llows: lot-(l" deepl(i" inside hottom diameter and 18" inside top diameter, with rover to tit. Outside stark T'-'approximately 6 in diameter at the base and "it" high. Air inlet t-l -ZT)" in diameter. Air draft regulating tnhe t l+ approximately 2" in length.

The essential feature of the invention is that the air inlet tuhe 11 is of surh proportions with respeet. to the stark and points in a direetion toward whit-h the air rut-rents are to he direeted within the rereptaele so that the up draft in the romparatively tall staek'i' will indure a down draft in the tuhe it and give surh velority to this down draft that will eause the air to sweep aeross the reeeding oil to pr dure the proper r inhuswhrrehv the up draft through the stark indures a down draft through the tuhe so that the inroniing air sweeps arross the surfaee of the oil in the rrreptaele. 2. ln an orrhard heater. the rom'hination of a fuel rontaining rereptaele havinga rlose lilting rover. said rover having a stark on its exterior and opening into the rerepta le,
